imbricate, subequal. Stamens 4, affixed to the corolla-tube, usually 
shortly exserted; filaments filiform; anthers I-celled by confluence. 
Ovary shortly 2-celled at the base, the septum disappearing above; 
style short, incurved and thickened at the apex; ovules many. Capsule 
subindehiscent or at length 2-valved; valves entire. Seeds small, 
ovoid, striate, somewhat rugose. — Small caespitose creeping or 
floating glabrous herbs, stemless or with stolon-like stems. Leaves 
radical or fascicled at the nodes, rarely alternate on some of the 
branches; petiole long; blade linear like the petiole or oblong-ovate 
or spathulate. Peduncles axillary, often shorter than the leaves, 
ebracteate. Flowers lilac, white or pale rose, usually small. 
Species 6 or 7, 2 of which are widely distributed in all temperate 
regions; 3 are limited to Tropical and South Africa, and 1 to Australia.

Prodrom. X, p. 426. — A small tufted glabrous annual aquatic or 
marsh herb, often producing stolons bearing one or more tufts of 
leaves and rooting at every tuft, sometimes with branches having 
alternate leaves. Leaves usually in radical tufts erect, suberect or 
floating, very variable in size and shape, narrowly spathulate to 
broadly oblong, sometimes linear; blade 2,5—20 mm long, 1 to 
10 mm broad, obtuse, entire; petiole 1—8 mm long, usually very 
slender. Flowers axillary, solitary; peduncles 2—22 mm long, erect 
or suberect in flower, often deflexed in fruit. Calyx about 2 mm 
long; teeth broader than long, minutely apiculate. Corolla lilac, 
white or pale rose, slightly longer than the calyx; lobes spreading, 
ovate-oblong, about 2mm long. Capsule subglobose, about 27/, mm 
in diam. — Flow. February to May.
